The objectification of women is not only the theme of the ludicrous and dreary romcom “Ruby Sparks” but its sustaining vision. Paul Dano, the most mannered and false young actor working in Hollywood, plays the vaguely antisocial author Calvin Weir-Field, whose first novel evoked comparisons to Salinger but who’s getting nowhere on his next. Until, that is, a wisp of a dream in which an apparition of a young woman beckons to him, and he can’t stop writing about her.
